Abstract:
Linear irreversible Carnot like heat engine in which the maximum efficiency is set to be and the
minimum efficiency (the efficiency at maximum power) is set to be it is effectively
optimized. The study investigated the Carnot like engine under the isothermal expansion and
compression parts.
In the isothermal expansion the working substance is thermalized with a hot reservoir during which it
release some amount of heat to the cold whereas in the isothermal compression is thermalized with cold
reservoir and absorbs some amount of heat from hot reservoir and the difference of the heat exchange
and the dissipation of the operation would give the net work done.
By employing a unified criterion for energy converters, the model of Carnot like engine is effectively
optimized and found to yield optimum finite-time thermodynamic quantities. This used to determine its
optimized periods, optimum power, efficiency and the scaled quantities. Efficiency-wise the optimized
efficiency is better than its value at maximum power, however, power-wise the maximum power is
greater than the optimized power. In the range of possibilities, the Carnot heat engine that optimized to
give a figure of merit is greater than one. The plotted against is about 1.43 as 0.773, So
that the optimized mode of operation is better than its maximum mode of operation for the
model
